Patented Sept. 6, 1932 NITED STATES VALERIANO CIURANA AND FEDERICO RANA, OF OAKLAND, GALIFORNIA SIGNAL Arm Application filed March 14,1932; Serial 110. 598,584.

This invention is a signal arm which is specifically adapted to provide the usual hand signals for indicating right and left hand turns and stops and is adapted to be mount-- 6 ed on the side of a car to be either manually or mechanically operated and which will clearly indicate to both approaching and following vehicles the intentions of the driver relative to the manipulation of the vehicle,

10 regardless of light conditions.

The main object of the invention is to provide a signal arm which is visible both forwardly and rearwardly and which is visible under all conditions of lighting. 7

Another object of the invention is to provide a signal arm as outlined with indirect artificial lighting means.

A further object of the invention is to provide a signal arm as outlined which is normally retained in inoperative position and which may be operated by a pull cord, either manually or by means of mechanically or electrically actuated devices and is particularly adapted to the electrically actuated mechanism in which a solenoid is employed.

Other objects and advantages of the invention will become apparent as the following description is read on the drawing forming a part of this specification and in which similar reference characters are used to designate similar parts throughout the several views of which:

Fig. l is a front view ofthe invention with the front housing plate removed. 2 Fig. 2 is a sideelevation of the inventio partly shown in section.

The invention consists of a sheath having one side wall 10, a front wall 11 and a back wall 12 in which the signal arm is normally disposed and concealed. j

The signal arm consists of a hollow element 13 formed in simulation of a hand and forearm and having a thumb 14, an extended index finger 15 and folded middle, third and r little fingers 16 and sides of the hand all outlined with spaced reflecting crystals or brilliants, and of. different colors on opposite sides, the front preferably being provided with orange or blue crystals 17 while the rear is provided with red crystals 18.

proximately at the center of the and, all

A large double brilliant 19 is'dis 0 6 1 P brilliants being set in aperturesin the walls of the hand.

A lamp mounting plate -20provided witha lamp socket 21 isremovably disposed Lat the ,end of the arm and is adapted to provide in- =direct lighting to the brilliants 17, 1 8 and IQ.

, Extensions 22 and 23 are formedin tgral. with, or secured to the arm 13 and areprovided with square apertures to fit the squared ends 2 1 of shaft 25} Extension 22 base groove peripherally formed to receive a condor cable 216 for operating the arm, the end of the cord bemg suitably secured as shown at '27. a

A spring drum 28 is mounted-on the side wall 10 of the housing as indicated at29,.an-d is provided with housings .30 in which ball bearings-31 are mounted, shaft 25 being mounted in the ball hearings to provide positive and frictionless movement of the arm.

Secured to shaft2 5 as indicated at 32 is a convolute spring 33 which has its other end secured to the spring drum as indicated at 34,

the spring normally retaining the arm within the housing.

Flexible terminal wires 35 are provided for the lamp. 36.

The device is normally concealed by the housing and is operated by pulling the cord;

26 by which the arm may be raised to Various positions to indicate left turn, right turn and stop. The indirect lighting illuminates the brilliants without producing glare so that the arm is at all times visible when the light is ,1.

burning, and made more intensely visible when the light rays from approaching or following vehicles are intercepted by the brilliants.

The large central brilliants are intended Having described an operative device it will be understood that variations in construction and arrangement of parts which are consistent with the appended claims may be resorted to without detracting from the spirit or scope of the invention or sacrificing any of the advantages thereof.

We claim:

1. A. signal arm comprising a. housing adapted to be secured to the side of an automotive vehicle, a hollow arm pivotally mounted and resiliently retained in said housing and terminating in a hollow hand outlined with a multiplicity of spaced brilliants and a large double brilliant intermediately disposed relative to the outlining brilliants vfor providing the effect of continuity of illumi,. q

nation over the entire surface of the hand, and, indirect lighting-means disposed in said arm for said brilliants.

2. .'A signal arm comprising a housing adapted to be secured to the side of an automotive vehicle, a hollow arm terminating in a hollovv hand and pivotally mounted and resiliently retained in said housing, said hand being outlined by a multiplicity of spaced brilliants on each side thereof, a large double :brilliantiintermediately disposed relative to the outlining brilliants whereby the effect ofcontinuity of illumination over the entire surface of the hand is produced, indirect,

lighting means disposed in said arm for illuminating the brilliants and means for operating said arm to move said arm to vari s Qus angular positions.

In testimony whereof We aflix' our signatures. Q i M v FEDERIGO'CIURANA.
